What's That Line? is a quest in Mario Party Advance.
In Mario Party Advance[]
The quest is initiated by Lakitu at his house after the player asks him about his favor. Lakitu proceeds to explain that he is a huge fan of Toad Force V, being able to quote nearly every line of dialogue from the show. However, he has forgotten one of the most famous lines from episode 28 entirely. He suggests that the player asks a fan of the show who lives in Mushroom Condo and sends them off. The only fan of Toad Force V in Mushroom Condo is Mushbert, who is on the first floor, and he is willing to explain the show to the player. The player can also ask him about episode 28, which he attributes to Jack and explicitly says is, "I'm an iron 'shroom."
Back at Lakitu's House, the player has to choose the correct quote from one of three options: "I'm just a 'shroom!", "I'm an iron 'shroom!", and "I'm no mushroom!" If the player picks one of the incorrect options, Lakitu disagrees with them and says that the line is from episode 30, "Fungicidal Maniac," forcing the player to restart the quest. When the correct option is selected, "I'm just a 'shroom!", Lakitu is overjoyed, and the quest concludes with him rewarding the player the Bait 'n Wait Gaddget.
